ALBERT O. SCOTT, OF SUMMIT, RHODE ISLAND.

CARRIAGE-JAC K.

SPECIFICATION forming part of Letters Patent No. 282,573, dated August '7, 1883.

Application filed January 2, 1883. (No model.) i I To all whom it may concern:

Summit, county of Kent,` and State of Rhode Island, have invented a new and useful Improvement in Carriage-Jacks; and I hereby declare that the following is a full, clear, and exact description of the same, reference being Vhad to the accompanying drawings, forming part of this specification.

This invention refers to an improvement in jacks for lifting and supporting the axles of buggies and other carriages, and is especially designed for light carriages.

- The invention consists in the peculiar and novel construction,by which the jack is made light7 more convenient in use, and cheap, as will be more fully set forth hereinafter.

Figure l is a view of my improved jack, p

showing the same in the position when supporting the axle of a carriage. Fig. 2 is an enlarged View, partly in section, of the stand and socket in which the post is secured. Fig. 3 is a view, .partly in section, of fthe post and the catch byV which the lift is supported.

In the drawings, a is the base on which the jack is supported. It is provided with projections at its under side, so as to lgive a iirm v support to the saine.

ing on theiioor. They are pushed about and4 liable to be broken.

The lifting-bar e is provided with the steps ff, either one of which may iit the height of the axle to be lifted. The lower end of the lifting-bar e is pivotally connected with the foot-lever g, supported on a fulcrum placed in the post c. The upper end of the lifting-bar passes through the slotted bracket l1, more clearly shown in Fig. 3. The lifting-bar e is provided with the stop e,whichlimits the rise of the same, and the pawl c2, by which it is supported on the bracket 11Ythe spring i keeping it in place when in use. The upper end of the lifting-bar is provided with the handle k7c,which,when pressed against or towardthe.

post c, releases the catch and allows the jack and its burden to descend.

The construction of the bracket is as follows: The slotted arm is provided with a screwthread, which enters the post c, and the support h is secured against the post by a'screw. The operation of the jack is as follows: It is first placed near the axle, so that one of the steps f f will be under the same. The foot is now placed on the foot-lever g,and the carriage is raised until the latch is thrown bythe spring i on the bracket-7L, when the weight is rmly supported, so that thewheel may be removed or turned in washing the same. When ready to be released, one nger kof the hand that holds Jche post near the top may be pressed on the handle k, and the lifting-rod will be instantly released, the foot may be placed on the foot-lever, and the carriage lowered slowly. The whole is so light and strong that it can be conveniently carried by one lhand and entered between the wheels of the carriage. When not required it can be hung on a nail or hook, ready for further use, and out of the way of harm. The round post @receives all the thrust endwise to the grain of the wood, and is therefore -able to sustain great weight, combining neatness and lightness vwith strength.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a carriage-jack, the combination,with the post o and base a, of the lifting-rod e, provided with the steps ff and the, handle k, the foot-lever g, the bracket h, the spring 13, the stop e, and the pawl el, -constructed substantially as described.

2. The combination, with the lifting-rod e, provided with a latch, the bracket h, and the foot-lever g, ofthe post c, provided with the wire eye d, constructed to suspend the jack, as described.

. ALBERT O. SCOTT.
